It sounds like from your post -- which I think does answer my question -- that each rechargable battery is made up of individual cells, which are of a set voltage. So there are the limits of physical space, until someone designs smaller cells, or something similar.

What part of my post didn't you understand??
Under the current laws of physics, NiCd and NiMH cells are 1.2 volts. Period. Case closed.
A "theoretical" 2 volt, putting out 1.5 volts is NOT possible given the current laws of physics, and stae of battery art.
A 2 volt cell would be lead acid under current tech. I don't really see anyone manfacturing a AA lead acid battery. Might be good because of voltage, but I damn sure wiuldn't want to carry it around.
Accept the fact that what is available now is probably all that's going to be available for a while. Evolutionary improvements, but that's about all.
My Aiwa boom-box runs great on 8 Dcell NiMH's, 4500 mah from Rat Shack. They last longer than alkalines.
My Kenwood pcdp and Aiwa pcp and 3 volt TAH all run great on Panasonic 1600 mah AA's from Costco.
My 9 volt TAH is running alkalines 9 v until I get a wall-wart. I'll use it stationary in the office.
BTW, anybody notice that those disposable batteries are named after a famous Baseball player??????
